Latest 4K drone footage of Apple's 'spaceship' Campus 2 shows landscaping, functional HVAC

The latest drone footage of Apple's new headquarters under construction shows the site more put together than in previous videos, with the entire site appearing to taking shape as a unified whole rather than disparate construction projects for the first time.

Instead of focusing on specific design features of the campus, the new video is more of an overview of the site than an update on specific feature completion.

The main building's solar installation appears to be about 40 percent complete. A satellite research and development facility looks nearly done, with the underground auditorium entrance further along, but still not yet complete.

Landscaping efforts have advanced significantly since the last video, with new trees having been planted in landscaping terraces since the last video. Additionally, preps for heavy work on the building's center core garden and pond are under way.

Apple's central power and HVAC plant is shown functioning, and more fuel cells have been installed along the garage next to the highway.

In 2011, Steve Jobs announced the project to the world, saying over 12,000 employees would work in the 2.8-million-square-foot "Spaceship" structure. Edible landscaping, walking paths, and other "green" improvements are in the process of construction, to minimize the impact the facility makes on the environment.

Apple's related Phase 2 adjacent project adds additional workspace, and includes a renewable energy-powered small data center.

Apple's micro-grid is reportedly capable of handling about 75 percent of Campus 2 power requirements during work hours, supplemented by Bloom Energy-provided fuel cells. Bloom Energy provided similar cells, currently in use at Apple's North Carolina data center.

The main Campus 2 project is expected to be completed by the end of 2016, with satellite facility construction extending into 2017.
